我想测试一个可以输入的文本框的字数,如果输入>70个字符的,就显示'发送内容过长,请重新输入！',如果<70,则显示'输入成功！'.
可我不知道该怎么显示示'发送内容过长,请重新输入！',
private void Page_Load(object sender, System.EventArgs e)

Label1.Text = Session["quanxian"].ToString().Trim();
name.Text = Session["username"].ToString();
if(!IsPostBack)

sqlDataAdapterbm.SelectCommand.Parameters.Add("@userid", SqlDbType.Char, 10).Value = name.Text.Trim();
sqlDataAdapterbm.Fill(dataSetbm,"faults");

DropDownList1.DataTextField = "teamname";
DropDownList1.DataBind();
